IMPROVEMENT IN WAGON-BRAKS.

Specitication forming part of Letters Patent No. 186,447, dated January23, 1877; application tiled October 29, 1875.

yTo all whom it may concern:

Be it known that I, 4ROBERT M. BAKER, of

Marcellus, Onondaga county, New York, have l invented a new and ImprovedWagon-Brake, of which the following is a specification Figure 1represents a top view, and Fig. 2 a vertical longitudinal section on theline c c of my improved wagon-brake.

Similar letters of' reference indicate corresponding parts.

The purpose of my invention is to furnish an automatic brake that shallbe simple `and cheap in construction and prompt in action, Withoutproducing a greater strain upon the parts than is necessary for thepurpose required, and that is instantly freed from action in backing.

The construction is as follows:

In the drawing, A represents a rod, which slides in a longitudinalrecess at the under side ot' the wagon-tongue, being connected'at "thefront end tothe neck-yokes of the horses d, is applied to the fulcrumedlever B, so as to force thereby'the tongue-rod in forward direction,and, simultaneously therewith, the brakeshoes away from the Wheels.

When the wagon is going downhill, the neck-yokes carry the sliding rodback, and apply, by the action of the fulcrumed lever, the brakes to thewheels with force just equivalent to the action of the animals upon theneck-yoke, and, releasing them as soon as on bifurcated rod b b, barC,hinged to the hounds,

and cam-brake D, constructed and arranged as and for the purposesspecified.
